[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] See also Figure 1 The remote control opening vehicle 100 in the preferred embodiment of the present invention includes a vehicle frame 110 , a lifting assembly 120 , a translation assembly 130 , an operating rod 140 and a controller 150 .

[0028] The frame 110 is a component that mainly plays a supporting and fixing role, so the frame 110 is generally made of materials with greater strength and rigidity, such as plastic steel, stainless steel, and aluminum alloy, to reduce the problem of deformation and breakage of the frame 110 during operation.

[0029] Please also read Figure 2, the lifting assembly 120 is mounted on the frame 110. Specifically, the lifting assembly 120 can be a telescopic rod structure. Moreover, one end of the lifting assembly 120 is fixed to the frame 110, and the other end is telescopic relative to the frame 110 along a first direction. Specifically in this embodiment, the first direction is a vertical direction.

[0030] The translation assembly 130 is installed at one end of the lifting assembly 120 away from the frame 110. The lifting assembly 120 can drive the translation assembly 130 to rise and fall in a first direction. Specifically in this embodiment, a lifting motor (not shown) is provided on the frame 110. The lifting motor is electrically connected to the lifting assembly 120. The lifting motor drives the lifting assembly 120 to drive the translation assembly 130 to rise and fall in the first direction, thereby realizing the adjustment of the height of the translation assembly 130. In actual operation, the heights of the opening switches of switch cabinets of different models and sizes are inconsistent. The setting of the lifting assembly 120 makes the remote control opening trolley 100 adjustable in height, so that it is suitable for switch cabinets of different heights and models, and enhances the practicality of the remote control opening trolley 100.

[0031] The operating rod 140 is mounted on the translation assembly 130. The operating rod 140 is generally made of epoxy resin, rubber or other polymer insulating materials. Specifically in this embodiment, the operating rod 140 is an epoxy resin operating rod. The operating rod made of epoxy resin has good insulation performance, small deformation shrinkage rate, and a certain degree of transparency.

[0032] The translation assembly 130 can drive the operating rod 140 to extend and retract along a second direction perpendicular to the first direction. Specifically in this embodiment, the second direction is a horizontal direction.

[0033] Therefore, the position of the operating rod 140 in the horizontal direction can be adjusted so that the operating rod 140 abuts against or separates from the opening switch.

[0034] Specifically in this embodiment, the translation assembly 130 includes an electric telescopic rod 132 and a sleeve 134. One end of the sleeve 134 is sleeved on the electric telescopic rod 132. One end of the operating rod 140 is accommodated and fixed on the end of the sleeve 134 away from the electric telescopic rod 132. The electric telescopic rod 132 is extended and retracted to drive the operating rod 140 to extend and retract along the second direction.

[0035] The frame 110 is provided with a driving motor 112 for driving the electric telescopic rod 132 to extend and retract. The driving motor 112 is electrically connected to the electric telescopic rod 132, and the operating rod 140 is connected to the electric telescopic rod 132 through a pipe sleeve 134. The driving motor 112 drives the electric telescopic rod 132 to extend and retract, driving the operating rod 140 to extend and retract along the second direction, so that the horizontal position of the operating rod 140 can be adjusted, that is, the distance between the operating rod 140 and the opening switch of the switch cabinet can be adjusted. When the operating rod 140 is extended, the operating rod 140 approaches the opening switch and then abuts against it; when the operating rod 140 is retracted, the operating rod 140 is separated from the opening switch. Therefore, the operating rod 140 can meet the needs of opening switches of various operating depths.

[0036] Specifically, the pipe sleeve 134 is a hollow structure, which can be made of aluminum alloy, plastic steel, polymer material or other materials. Specifically in this embodiment, the pipe sleeve 134 is an aluminum alloy pipe sleeve. The pipe sleeve 134 made of aluminum alloy is acid and alkali resistant, has strong corrosion resistance and good heat resistance, which is convenient for extending the service life of the pipe sleeve 134.

[0037] Furthermore, in this embodiment, the translation assembly 130 further includes an elastic member 136 . The elastic member 136 is received in the sleeve 134 , and two ends of the elastic member 136 are respectively connected to the inner wall of the sleeve 134 and one end of the operating rod 140 .

[0038] Due to inertia or visual blind spots, when the operating rod 140 contacts the switch cabinet, the electric telescopic rod 132 cannot stop moving immediately. After the operating rod 140 contacts the opening switch, the end of the operating rod 140 away from the pipe sleeve 134 stops moving, while the end sleeved on the pipe sleeve 134 continues to move under the drive of the electric telescopic rod 132, which may cause damage to the operating rod 140 or the operating rod 140 to separate from the pipe sleeve, affecting the normal use of the remote control opening trolley 100. The setting of the elastic member 136 can form an elastic force between the inner wall of the pipe sleeve 134 and one end of the operating rod 140, so that the inner wall of the pipe sleeve 134 and the operating rod 140 are in elastic contact, and a certain buffer time is reserved for the electric telescopic rod 132 to stop moving, thereby protecting the operating rod 140.

[0039] Furthermore, the elastic member 136 is a compression spring, and two ends of the compression spring are respectively in contact with the inner wall of the sleeve 134 and one end of the operating rod 140 .

[0040] The compression spring is a common component of the elastic member 136, which is easy to obtain and inexpensive, and is conducive to reducing the production cost of the remote control opening trolley 100. At the same time, when the operating rod 140 is damaged, since the two ends of the compression spring are respectively in contact with the inner wall of the pipe sleeve 134 and one end of the operating rod 140, the operating rod 140 can be directly removed from the pipe sleeve 134, which facilitates the removal and replacement of the operating rod 140.

[0041] In this embodiment, the operating rod 140 includes an elastic rubber pad 142 . The elastic rubber pad 142 is disposed at an end of the operating rod 140 away from the sleeve 134 .

[0042] The provision of the elastic rubber pad 142 can prevent the operating rod 140 from being damaged due to rigid contact with the opening switch, thereby extending the service life of the operating rod 140 .

[0043] Specifically, the elastic rubber pad 142 can be made of rubber, sponge, foam or other materials. It only needs to ensure that the elastic rubber pad 142 can generate a buffering force to avoid rigid contact between the operating rod 140 and the opening switch.

[0044] The controller 150 is electrically connected to the lifting assembly 120 and the translation assembly 130. The controller 150 is used to receive a remote control signal and control the lifting assembly 120 to rise and fall and the translation assembly 130 to extend and retract according to the remote control signal.

[0045] Through the setting of the controller 150, the remote-controlled opening trolley 100 can still perform lifting and translational movements without the need for an operator to approach, and then abut against the opening switch for emergency opening, thereby avoiding casualties caused by an explosion in the switch cabinet during the opening process and improving the safety of the remote-controlled opening switch.

[0046] Specifically in this embodiment, the controller 150 includes a first controller and a second controller. The first controller and the second controller are respectively arranged in the lifting motor and the driving motor 112. In addition, the remote control opening trolley 100 is also provided with a remote controller (not shown) for remotely controlling the first controller and the second controller. The remote controller can send a remote control command for lifting to the first receiver, and the first controller receives the remote control command for lifting, triggers the lifting motor to drive the lifting assembly 120 to lift, thereby driving the translation assembly 130 and the operating rod 140 to lift in the first direction. The remote controller can also send a remote control command for telescopic to the second controller, and the second controller receives the remote control command for telescopic, triggers the driving motor to drive the translation group 130 to telescope in the second direction, thereby driving the operating rod 140 to telescope in the second direction.

[0047] Specifically, the controller 150 may be an infrared remote control controller, a radio remote control controller or other forms of controllers, and it is only necessary to ensure that the remote control opening trolley 100 can achieve remote control.

[0048] In this embodiment, the remote control opening vehicle 100 further includes an infrared locator 160 . The operating rod 140 has a receiving cavity 144 . The infrared locator 160 is received and fixed in the receiving cavity 144 . The infrared locator 160 is used to emit an infrared laser that coincides with the second direction.

[0049] The infrared laser emitted by the infrared locator 160 coincides with the second direction, and the operator can observe whether the infrared laser beam is aligned with the opening switch within a range of more than 30 meters. When the focus of the infrared laser beam is located at the opening switch, it means that the operating rod 140 is facing the opening switch, and the electric telescopic rod 132 can be operated to drive the operating rod 132 to extend and retract. Therefore, the operating rod 140 abuts against the opening switch to achieve emergency opening.

[0050] It should be pointed out that in other embodiments, the infrared locator 160 can also be a red light LED lamp, or other locators that can emit visible laser beams. It only needs to ensure that the light beam emitted by the infrared locator 160 is visible when it is facing the disconnect switch within a range of more than 30 meters.

[0051] In this embodiment, the remote control opening trolley 100 further includes a longitudinal adjustment component 170 , and the translation component 130 is installed on the lifting component 120 via the longitudinal adjustment component 170 . The longitudinal adjustment component 170 can drive the translation component 130 to slide along the second direction.

[0052] By setting the longitudinal adjustment component 170, the sliding range of the translation component 130 along the second direction is expanded, so that the remote-controlled opening switch trolley 100 can achieve contact between the operating rod 140 and the opening switch without close contact with the switch cabinet, thereby enhancing the application range of the remote-controlled opening switch trolley 100.

[0053] Furthermore, in this embodiment, the longitudinal adjustment assembly 170 includes a linear guide rail 172 extending along the second direction, a slider 174 and a translation motor (not shown in the figure), the translation assembly 130 is arranged on the slider 174, and the translation motor is used to drive the slider 174 to drive the translation assembly 130 to slide along the linear guide rail 172.

[0054] The linear guide 172 is provided with a screw rod 1722, which is in transmission connection with the translation motor. The frame 110 is provided with a button for controlling the translation motor to start and stop. When the start button is pressed, the translation motor runs to drive the screw rod 1722 to rotate, and the slider 174 provided on the linear guide 172 drives the translation assembly 130 to move along the linear guide 172 under the drive of the screw rod 1722, so as to achieve translation in the second direction. When the slider 174 and the translation assembly 130 move to a suitable position, the shutdown button is pressed, the translation motor stops running, and the movement of the slider 174 and the translation assembly 130 in the second direction stops.

[0055] The linear guide rail 172 and the translation motor are used to drive the translation assembly 130 to move along the second direction. The driving mode is simple to operate and the movement is smooth, which facilitates the normal operation of the remote control opening trolley 100.

[0056] It should be noted that, in other embodiments, the translation motor may also be electrically connected to the slider 174. The translation motor drives the slider 174 to drive the translation assembly 130 to move along the second direction.

[0057] Please also read Figure 3 In this embodiment, the remote-controlled gate opening trolley 100 also includes a lateral adjustment component 180, and the translation component 130 is installed on the longitudinal adjustment component 170 through the lateral adjustment component 180. The lateral adjustment component 180 can drive the translation component 130 to drive the operating rod 140 to move along a third direction perpendicular to the first direction and the second direction.

[0058] When the operating rod 140 approaches the switch cabinet and deviates from the opening switch, the lateral adjustment assembly 180 drives the translation assembly 130 to drive the operating rod 140 to move along the third direction, so as to achieve fine adjustment of the operating rod 140 in the third direction, so that the operating rod 140 can approach and align with the opening switch of the switch cabinet in the third direction. Specifically in this embodiment, the third direction and the second direction are surrounded to form a horizontal plane. The first direction is perpendicular to the horizontal plane.

[0059] Furthermore, in this embodiment, the lateral adjustment assembly 180 includes an adjustment rail 182 and an adjuster 184 . The translation assembly 130 is disposed on the adjustment rail 182 . The adjuster 184 is installed at one end of the adjustment rail 182 to drive the translation assembly 130 to drive the operating rod 140 to move along the adjustment rail 182 .

[0060] A lead screw is provided on the adjustment rail 182, and the translation assembly 130 is connected to the lead screw in a transmission manner. The regulator 184 provided at one end of the adjustment rail 182 rotates to drive the lead screw to move, thereby driving the translation assembly 130 and the operating rod 140 to move along the third direction to achieve fine adjustment of the position.

[0061] The arrangement of the adjusting guide rail 182 and the adjuster 184 makes the movement of the operating rod 140 in the third direction highly controllable and easy to operate.

[0062] It should be noted that, in other embodiments, the lateral adjustment assembly 180 may also be provided with a motor, and the motor is used to drive the translation assembly 130 to move along the adjustment guide rail 182 .

[0063] The frame 110 is also provided with a control panel 114 and a power connector 116. The power connector 116 is connected to a power source to provide power for the remote control opening trolley 100. In addition to the buttons for controlling the start or shut down of the translation motor, the control panel 114 is also provided with a power switch and a button for controlling the operation or shutdown of the infrared locator 170. When the operation button of the infrared locator 160 is pressed, the infrared locator 160 emits an infrared laser. When the shutdown button of the infrared locator 160 is pressed, the infrared locator 160 stops emitting an infrared laser.

[0064] In addition, a power supply circuit for controlling the operation of the remote control opening trolley 100 is also provided on the frame 110. When the power connector 116 is connected to the indoor power supply, the power supply unit starts to work. Specifically in the present embodiment, the remote control opening trolley 100 is powered by a 220V AC power supply. The infrared locator 160 is powered by a 5V DC power supply, and the lifting motor, the translation motor and the drive motor 112 are all powered by a 24V DC power supply, all of which are rectified internally by the power supply unit. The lifting motor, the translation motor and the drive motor 112 are all connected through the positive and negative poles, and the forward and reverse control of the lifting motor, the translation motor and the drive motor 112 are respectively completed, so as to realize the lifting, translation and extension of the operating rod 140.

[0065] In this embodiment, two universal wheels 117 and two anti-skid casters 118 are also provided at the bottom of the frame 110. A lock is provided on the universal wheel 117. The universal wheel 117 is flexible and convenient to move, and the setting of the anti-skid casters 118 and the lock can ensure that the remote control opening trolley 100 does not move during the working process, and has high reliability. The handrail 119 is fixed on the frame 110. When the remote control opening trolley 100 is working, the handrail 119 is pushed, and the frame 110 moves under the action of the universal wheel 117 and the anti-skid casters 118 and approaches the switch cabinet. Then, the start and stop buttons of the translation motor on the control panel 114 are operated to achieve the rough adjustment of the position of the translation assembly 130. Furthermore, the operator is away from the switch cabinet, and controls the lifting and extension of the translation assembly 130 through remote control, and the operating rod 140 abuts against the opening switch to achieve the emergency opening of the switch cabinet.

[0066] Please also read Figure 4 In this embodiment, the remote control opening trolley 100 is also provided with a shell (not shown) used in conjunction with the frame 100. When the remote control opening trolley stops working, the shell can be placed on the frame to seal the remote trolley for storage.

[0067] The above-mentioned remote control trip trolley 100, the lifting assembly 120 is installed on the frame 110. When the controller 150 receives the lifting signal, the lifting assembly 120 drives the translation assembly 130 to lift and lower along the first direction; when the controller 150 receives the translation signal, the translation assembly 130 drives the operating rod 140 to extend and retract along the second direction. Therefore, the operating rod 140 can abut against the trip switch after rising or falling along the first direction and extending and contracting along the second direction, thereby realizing the remote control of the switch cabinet trip. Since the above-mentioned remote control trip trolley 100 does not require manual approach for tripping, casualties caused by the explosion of the switch cabinet during the tripping process are avoided. Therefore, the above-mentioned remote control trip trolley 100 has a higher safety performance.

[0068] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
